@moneystocker: 6.5% interest with XTB (ad)! You can get a boosted rate of 6.5% interest on uninvested cash within the XTB Stocks ISA for 3 months (4.5% normally). The Stocks ISA is usually for investing (which carries risk). But the uninvested cash within that account can grow too. It’s held in a bank which has FSCS protection up to £85,000 – so it’s safe to use. XTB have a flexible Stocks ISA, which means you can withdraw the money and put it back in the same tax year without losing your allowance. They’re a 0% commission broker* with no platform fee (other fees may apply), and they have a compelling offering. Here’s the legal bit: *for monthly turnover equivalent up to 100,000 EUR. Transactions above this limit will be charged a commission of 0.2% (minimum of 10 GBP). Other fees may apply. Capital at risk. The value of your investments may go up or down. Tax treatment depends on your individual circumstances and ISA regulations which may change. A 2% AER boost will be added to the standard variable interest rate on your free ISA funds for the first 90 days. T&Cs apply. #investing
